The Complete Stack for Running AI Agents 24/7 on a Mac ($0/month)

I've been running 12 autonomous AI daemons on a single MacBook for weeks. Here's the full stack — what each daemon does, how they talk to each other, and why it costs nothing.

The 12 Daemons

Daemon What It Does Frequency
brain-pipe Extracts session logs, truncates, feeds to categorizer 10 min
llama-categorize Local Llama 3.2 1B routes entries to project files On trigger
brain-filer Files categorized entries, rebuilds brain-index.md On trigger
stripe-monitor Checks for new Stripe payments 60 sec
wallet-watch Monitors SOL wallet balance 5 min
market-scout Tracks SOL + BTC, alerts on 5% moves 5 min
predator Autonomous crypto trading (Kraken API) 5 min
devto-engine Writes + publishes technical articles 6 hr
blog-gen Generates SEO blog posts Daily
github-outreach Finds + comments on relevant GitHub issues 4 hr
openclaw-watch Monitors upstream OpenClaw repo for changes 6 hr
gmail-leads Auto-replies to website leads 15 min

The Memory Layer

The biggest problem with AI agents: they forget everything between sessions.

The fix: a 3-stage pipeline that runs every 10 minutes.

  1. Extract: brain-pipe.sh reads the last 50 messages from the session JSONL, truncates each to 300 chars (2KB cap)
  2. Categorize: llama-categorize.sh runs Llama 3.2 1B locally — routes each entry to a project category with summary + tags
  3. File: brain-filer.sh appends to project-specific markdown files, rebuilds brain-index.md

Next session, the agent reads brain-index.md and picks up exactly where it left off. Zero cloud cost. Zero vector database. Just markdown files and a local LLM.

The Secrets Vault

27 API keys stored in macOS Keychain:

# Store a key
security add-generic-password -s "magic-vault" -a "STRIPE_SECRET_KEY" -w "sk_live_..."

# Retrieve at runtime
STRIPE_KEY=$(security find-generic-password -s "magic-vault" -a "STRIPE_SECRET_KEY" -w)
Enter fullscreen mode Exit fullscreen mode

Encrypted at rest. Requires login password. Never appears in any config file, git repo, or environment variable.

The Revenue Monitor

stripe-monitor.sh checks every 60 seconds:

LATEST=$(curl -s "https://api.stripe.com/v1/charges?limit=1&status=succeeded" \
  -u "$STRIPE_KEY:" | jq -r .data[0].created\)

if [ "$LATEST" -gt "$LAST_KNOWN" ]; then
  # New sale! Telegram alert.
fi
Enter fullscreen mode Exit fullscreen mode

Every sale triggers an instant Telegram notification. Revenue logged to JSONL for analysis.

The Trading Engine

predator.sh runs a momentum strategy on Kraken:

  • Checks SOL price every 5 minutes
  • Buys when price crosses above 20-period SMA
  • 5% hard stop-loss, 10% take-profit
  • All trades logged, all alerts via Telegram

Total Monthly Cost: $0

Ollama (local LLM) $0
launchd (daemon manager) $0 (built into macOS)
Vercel (hosting) $0 (hobby tier)
Cloudflare (CDN/DNS) $0 (free tier)
